The present experimental studies are carried
out to identify the existence of input multiplicity in a non-isothermal CSTR. The sulfuric acid catalyzed hydrolysis
of acetic anhydride reaction system has been chosen and the regions of existence of input multiplicity are theoretically
identified. The reactor showed the same steady state temperature for two input flow rates of reaction
mixtures into the CSTR reactor and thus confirming the existence of input multiplicity for the sulfuric acid
catalyzed hydrolysis of acetic anhydride reaction system. It was observed that the time taken by the reactor
was too long at a low feed flow rate of reaction mixture than at a higher feed flow rate reaction mixture. The
model simulations of steady state temperatures were in close agreement with experimental data for the above
feed flow rates of reaction mixture conditions
